DELAFIELD- Former Democrat Kevin Nicholson has officially announced that he is running for U.S. Senate against Tammy Baldwin. Nicholson has been plagued by bad press lately. He has been caught poll-testing his past as a Democrat, a former roommate has criticized him over Twitter, and he has been criticized for inaction while serving on the state’s Veterans Affairs board. Despite this, Nicholson is moving forward, and insisting that he is the outsider that Wisconsin needs. This claim is particularly interesting when one considers his deep ties to big donors and big business.

The Associated Press and Wisconsin Public Radio report:

A former Marine and former Democrat has become the first Republican to get into the race to challenge Democratic U.S. Sen. Tammy Baldwin next year.

Republican Kevin Nicholson of Delafield launched his campaign Wednesday with a video that casts himself as a “conservative outsider” and emphasizes his military service.

Nicholson was expected to get into the race. A political action committee supporting him that’s backed by Uline Corp. founder Richard Uihlein has already raised $3.5 million to back his candidacy.

Other Republicans considering getting into the race include state Sen. Leah Vukmir, Madison businessman Eric Hovde and state Rep. Dale Kooyenga.
